TABLE-LOCK.

SPECIFICATION forming part of Letters Patent No. 759,312, dated May 10,1904.

Application filed April 20, 1903- Serial No. 153,553. (No model.)

To (alt. whom it may concern.-

Be it known that I, J OHN K. RIsHEL. a citi zen ot the United States,residing at VVilliamsport, in the county of Lycoming and State ofPennsylvania, have invented a new and useful Table-Lock, of which thefollowing is a specilication.

This invention relates to table-locks, and is particularly designed foruse in securely locking together the parts of a pedestal extensiontableto counteract any tendency of the podestal parts to sag or spread apart.

Another object of the invention is to provide means within convenientreach which can be expeditiously and effectually operated to connect orrelease the separate pedestal parts.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims, it being understoodthat various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any 01 the advantages of this invention.

In the drawings, Figure 1 is a side elevation of an extension-tablecontaining my invention, the table-top and pedestal being broken awayand shown in vertical section, disclosing the interior parts of themechanism. Fig. 2 is a detail side elevation of the lock applied to theinterior of the pedestal,presenting the operating parts of the lockingmechanism prior to their engagement; and Fig. 3 is a detail top planview of the operating-lever.

The reference-numerals 1 and 2 designate two table-top sections carriedby the hollow pedestal-sections 3 and 4:, which are supported upon thespread feet 5 and 6. The pedestal formed by the two complementarymembers 3 and 4 is of the box form, so as to encompass the center leg 7,the lower end of which projects therethrough, so as to rest upon thefloor.

When the pedestal parts are brought together, as shown in Fig. 1, anypressure upon the table-top will be transmitted upon the spread feet,and the tendency will be to spread, so as to cause an unsightly creviceor seam to occur, as well as weaken the table throughout.

In order to overcome or counteract the tendency of the parts to spread,I provide a locking device which consists of a lever-operated pivotedcatch carried by one of the pedestalsections and engaging acomplementary part on the opposing pedestal-section.

The catch is designated by the referencenumeral 8 and is illustrated asbeing pivotally mounted to a bearing-plate 9, secured to one of thepedestal-sections and in line with the complementary part 10, comprisinga pin carried by the opposing pedestal part and which is adapted to beengaged by the hook-shaped terminal 11, forming a part of the catch 8.

In order to prevent a displacement of the catch, as well as to limit itsmovement, I pro- 5 vide a guide-loop 12 on the plate 9, through whichthe catch projects.

An operating mechanism is provided for the catch, which consists of avertically-disposed and pivoted lever 13, movable on its fulcrum 14 by ahorizontal handled lever 15, connected to the lever 13vby a link 16. Thecurved toe 17 of the lever 13 engages the projection 18 on the catch 8to release the catch from engagement with part 10; but if it is desiredto cause 7 5 the pedestal parts to become locked a movcment of thehandle 15 will cause the lever 13 to engage the top edge of thecatclnand thereby force it into engagement with the part 10, where itwill be retained until the handle-lever 15 is reversed to cause the toe17 of the lever 13 to engage the projection 18 to release it.

In actual practice the catch 8 will be terminally pivoted at the endopposite to that at 5 which the hook 11 is carried, and the projection18 is inclined at an acute angle to the longitudinal edges of the catch,so as to provide means wherebya quick-positive action can be imparted tothe catch, whether the pedestal 9 parts are being released or connected.The handle-lever 15 will preferably be located beneath one of the tabletop sections so as to be within easy reach of the operator, and as thepoint of connection of the link with the lever 15 is at an eccentric tothe point of connection of the lever with the table said lever will beheld in either position to which itis adjusted.

Having thus described the invention, what I claim is 1. In a pedestalextension-table the combination with a vertically-divided pedestal andthe two separable parts of the table-top carried by the pedestal parts,of means for securing the pedestal parts together, comprising alatch-bar on one of the pedestal parts for engagement with acomplementary device on the other pedestal part, terminally pivoted tothe pedestal part and having an inclined projection at one end, and alever carried by the said pedestal part having a toe for contact withthe inclined projection to release the latch-bar, and movable to bearupon a point intermediate the ends of the latch-bar to hold it inengagement with the complementary device.

2. In a pedestal extension-table, the combination with avertically-divided pedestal and the two separable parts of the table-topcarried by the pedestal parts, of means for securing the pedestal partstogether, compris= ing a pivoted catch on one of the pedestal parts forengagement with a complementary member on the adjacent pedestal part, afor Wardly-disposed projection on the catch, and a lever pivoted to thepedestal part on which the catch is secured, said lever having a toe forengagement with the projection to re lease the catch and movable to apoint intermediate the ends of the catch so as to bear thereon and holdthe catch in a locked position.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.

JOHN K. RISHEL.
